4 Claims. 1

This invention relates to sinks and particularly to improvements in thattype 'known as a shampoo sink, used extensively'inbeauty parlors andbarber shops for shampoos, cold waves, color rinses, and similartreatments in which liquids are applied to the hair.

This type of sink is ordinarily used by having the customer lean everitand the liquid drains into the sink. However, inapplying hair dyes. coldwave liquids, or color rinses, the liquid must be-caught'and re used byapplying it to the hair until the treatment is completed. Conventionalshampoo sinks provide very unsatisfactory and inadequate equipment forcarrying out "these treatments for they have no 'means to collect theliquid :for reuse and a separate bowl or pan must be employedto'catch-the liquidso that it may be reapplied to complete thetreatment.

An object of the present invention, therefore, is to provide an improvedshampoo sink in which small quantities of dyes, rinses, and the like,may be collected for re-use.

A specific object is the provisionof a sink having a readily removableimperforate cup in the drain opening which is adaptedto collect liquidwhen desired, but which-may be removedat other times to permit thesame-to 'be used in the eonventional manner.

Another object is an improved hair rinse apparatus comprising a sink anda pair of cups which fit alternately within'the two drain openings, the.cups being employed alternately, one as a supply for used hair rinse,and the other as a receptacle in the drain opening for collecting it forre-use.

Other obiects'and advantages will become apparent from the followingdescriptionlin connection with the drawings, in which? Figure 1 is aperspective view of a shampoo sink embodying one form of my inventionshowing the imperforate liquid collecting cup in place;

Fig. 2 is a sectional view of the drain bowl portion of Figure 1 showingthe details ofthelconstruction;

.Fig. 3 is a view similar to Figure 1 with the collecting cup removed,and

Fig. 4 is a sectional view of 'Fig. 3, similar to Fig. 2.

Referring nowrmoreparticularly to the drawings, the sink I may be of anypreferred shape and, in the present instance, is provided with aconventional water faucet assembly 2 and sham poo nozzle 3 on the end ofthe usual flexible hose (not shown).

The sink bottom 4 will be formed with an opening 5 communicating througha bowl portion .6 with a drain pipe I. As shown the cross sectionalareaof the bowl portion 6 is considerably larger than the crosssectionalarea of the drain pipe I. The bowl 6 may be an integral part of thesink, as shown, or it .may be a separate member if preferred. The bottomof the sink immediatelyaround the opening-5 will be depressed, asat .8,preferably so the parts within the bowl do not extend above the topsurface 9 of the sink bottom 4. lmmediately'within .the bowl is seated aperforate cup or strainer I I having the holes 12 in the bottom thereofand having an exteriorly turned flange i3 mounted upon the depressedsurface or annular recess -8 whichdefinesan upwardly facing annularshoulder encircling the drain bowl by means of screws 14. Within thestrainer I! an imperforate collecting cup 16 of substantial or sizablecapacity is positioned, being seated by. its outwardly turned flangeportion i1 upon the upper part of the strainer and being readilyremovable by means of the upstanding hook or lifting element 18 which ismounted in the bottom of the cup. Preferably the cross-sectional area ofthe perforate cup is substantially larger 'than the cross-sectional areaof the drain and slightly smaller than that of the drain bowl so thatthe perforate .cup can be received in the drain bowl and thecross-sectional area of the imperforate cup is larger than thecross-sectional area of the drain and slightly smaller than thecross-sectional area of the perforate cup so that the imperforate cupcan be received in the perforate cup. The depth of the depressed surface8 will preferably be such that when the parts are assembled, as shown inFig. 2, the top of the collecting cup iii will be level with or belowthe surface '9 so that the greatest part of the liquid dropping in thesink will flow off of the surface 9 intothe cup l6, thereby makingavailable for re-use the greatest possible amount of liquid flowing intothe sink. This is an important feature because many rinsing and dyeingsolutions are expensive, hence are used in relatively small quantities,and it is essential that as little as possible be lost down the draineach time the collecting cup is removed and replaced by an empty one.

While I have shown a strainer II, which will be preferred in most casesto prevent the loss of jewelry and other articles down the drainpipe,this is not an essential part of my invention inasmuch as it may bedispensed with entirely, in which case the collecting cup I6 will beproportioned to fit directly upon the depressed surface 8 of the sinkbottom. In either case, the collecting cup flange I! will preferablymake a substantially leak-proof seal with its engagin surface (eitherthe strainer II or the depressed surface 8) so as to minimize liquidloss by leakage. It need not necessarily be perfectly leak-proof1nasmuch as a slight amount of leakage will not be objectionable.

My improved sink will be employed in the following manner, assuming, forexample, that it is to be employed in giving a hair color rinse in abeauty shop: A collecting cup [6 will be placed in the drain opening asshown in Fig. 2. The customer will lean over the sink and the operatorwill apply a quantity of rinsing solution to the customers hair and itwill flow into the sink. The quantity employed will usually be less thanthe capacity of the collecting cup and when it is all collected thefilled cup IE will be removed by the lifting element l8, as shown inFig. 3, and replaced by an identical but empty collecting cup. The usedsolution will be re-applied to the hair and recollected in the secondcup, the solution being re-used over and over again until the treatmentis completed.

While a particular form of the present invention has been shown, it willbe apparent that minor changes will readily suggest themselves to othersskilled in the art without departing from the spirit and scope of theinvention.

Having thus described the invention, what is claimed as new is:

1. Means for treating hair or the like with a relatively smallquantityof solution and re-using the same solution until the treatmentis com pleted comprising a sink for receiving the solution flowing fromthe hair and having a bottom and a drain bowl in communication with adrain opening on the bottom thereof, a pair of cups of substantialcapacity, each shaped to fit in said drain bowl below the top surface ofsaid sink bottom, and means formed on each of said cups shaped to coactwith the sink to support them in the drain bowl, one of said cupsnormally being disposed in said drain bowl and collecting hair rinse ordye solution flowing into the sink after it is poured over a customershair and the other of said cups normally being used to pour previouslycollected solution over the customers hair.

"2. In combination, a sink for beauty parlors and the like having abottom and an annular recess formed on the top surface of said'bottom todefine an upwardly facing annular shoulder, a drain bowl on the bottomof said sink positioned to be encircled by said shoulder and arranged tocommunicate with a drain opening, said drain bowl being shaped to have acrosssectional area substantially larger than that of the drainopening,;a perforate cup shaped to have a cross-sectional areasubstantially larger than the drain opening and slightly smaller thanthe crosssectional area of the drain bowl to permit reception of theperforate cup in the drain bowl, said cup having a flange shaped to bereceived in said annular recess and to rest on said annular shoulder tosupport said cup in said bowl and being shaped to be disposedsubstantially cup in the perforate cup, said imperforate cup having aflange shaped to be received in said annular recess and to rest on theflange of the perforate cup to support the imperforate cup and beingshaped to be disposed below the top surface of the bottom of the sinkwhereby the contents of the sink can drain into the imperforate cup.

3. In combination, a sink for beauty parlors and the like having anannular recess encircling the drain bowl to define an upwardly facingannular shoulder, a drain bowl on the bottom of the sink positioned tobe encircled by said annular shoulder and arranged to communicate with adrain opening, said drain bowl having a larger cross-sectional area thanthe drain opening, a perforate cup shaped to be removably disposed insaid drain bowl and having an exterior flange shaped to be received insaid recess and to rest on said shoulder, an imperforatecup shaped to beremovably disposed in said perforate cup and having an exterior flangeshaped to be received in said recess and to rest upon the upper edge ofsaid perforate cup to form the sole support for said perforate cup andto effect a'seal between the sink and the drain, and a lifting elementaffixed to said imperforate cup for facilitating the manual handling ofsaid imperforate cup.

4. In combination, a sink for beauty parlors and the like having abottom and an annular recess formed on the top surface of said bottom todefine an upwardly facing annular shoulder, V
